The in 1 shown container 1 includes one from an outer layer 2 folded outer box, in which one from an inner layer 3 folded inner frame is inserted. The outer box comprises a cover element 4 , which has a bent edge 4a pivotally connected to the rest of the outer box and which is a peripheral area 4b having, by prior tearing off a tearable strip element 5 (please refer 2 ) was formed and the separation between the cover element 4 and remaining outer container represents.

The cover element 4 covered in the closed state over the boundary 4b the outer box protruding portion of the inner layer 3 , It is one of the material of the inner layer 3 existing counterpart 6 on the inside of a front portion of the lid member 4 glued. This counterpart 6 corresponds to a closing tab 7 attached to a front upper edge 22 the inner situation 3 in the form of a connected via a bend line extension of the inner layer 3 is arranged.

Upon a first opening of the cover element 4 after previously the strip element 5 has been removed, the lid member 4 along the bend 4a around the back wall 13 the carton 2 be panned. The cover element 4 is connected by a bending point with the trunk, whereby the cover 4 and hull are combined in one cut. The bending point is hinged, z. B. formed by folding, scratches, grooves, perforations, upsetting or folding.

The outer box is made of the outer blank or the outer layer 2 folded (see also 2 ), this being a front wall 10 has, over the crease lines 8th right and left side walls 11 . 12 connect, taking to the one side wall 11 again a back wall 13 of the container 1 followed. The back wall 13 has a glue flap 15 on, by means of which the gradual 90 degrees to each other kinked segments 10 . 11 . 12 . 13 the outer box are glued together to form a closed peripheral wall. The strip element 5 that's a first end 14 and a second end 15 has, extends over both side walls 11 . 12 as well as the front wall 10 , Each of the walls 10 . 11 . 12 . 13 has on each of its front pages each one over creasing lines 23 split tab 10a . 10b . 11a . 11b . 12a . 12b . 13a . 13b on. In this case, the lid member from the tabs 10a . 11a . 12a . 13a as well as through the tear-off strip 5 separated areas of the walls 10 . 11 . 12 educated. A bottom of the container is through the tabs 10b . 11b . 12b . 13b educated.

From the second end 15 to the fulcrum 16 the line of weakness extends 9 , A detailed view D of this area of the folding blank is in 4 and 5 and will be described in more detail below.

The inner situation 3 has a total of five segments 3a . 3b . 3c . 3d . 3e on (see also 3 ), which have crease lines or creasing lines 8th folded in the folded state in each case by 90 degrees with respect to an adjacent segment. The segment 3b and the segment 3c overlap in the folded state and are glued together, so that these two segments together form a side wall of the inner layer. The closing tab 7 is over a crease line 7a at the first segment 3a set or when cutting the inner layer 3 have been left standing.

4 shows a detail top view D on the blank of the side wall 11 the outer box 2 with the second end 15 the tearable strip element 5 and the line of weakness 9 to the fulcrum 16 the lid element 4 in the unopened state.

The strip element 5 is shown in a partially opened state. Behind the strip element 5 is hatched the side wall 6e the inner frame 3 to see. The strip element 5 is before the first opening of the cover element 4 completely from the outer layer 2 separated, leaving the only remaining connection between the sides wall 11 and the lid member 4 the line of weakness 9 is.

The line of weakness 9 indicates one of the direct, straight connection 17 between endpoint 15 the tearable strip element 5 and the fulcrum 16 the lid element 4 deviating course, in the form of a convex arc on.

The line of weakness 9 is formed as a slot perforation, the slot-shaped material bridges M between the lid member 4 and the side wall 11 and slot-shaped perforation openings P has.

The tangent T of the weakening line 9 at the endpoint 15 makes with the straight connection 17 an angle α. The angle β is formed by the fiber direction F of the outer layer 2 and the tangent T of the line of weakness 9 at the endpoint 15 , wherein the fiber direction is substantially horizontal, ie a 90 ° angle to the buckling or creasing lines 8th forming, lost.

As further out 4 is apparent, is between the tear point 19 the line of weakness 9 and the endpoint 15 a straight line scribe line 18 arranged and forms an extension to the tear-off 20 of the strip element 5 ,

5 shows the off 4 known arrangement at the beginning of opening the lid member 4 , How out 5 visible, first raises the cover element 4 lightly without first causing tearing of the perforation 9 comes. Will the cover element 4 as indicated by the arrow, continue around the turning point 16 pivoted, begins the perforation line 9 starting at the endpoint 5 to break up sequentially.

Another embodiment of the weakening line 9 is in 6 shown. The weakening line is formed as a perforation, which has a deviating from a straight, arc-shaped course, wherein the perforation comprises lines of weakness, which have a deviating from a tangential to the arcuate orientation. As in 6 can show the lines of weakness 9 For example, have an orientation parallel to the bottom of the container orientation. By this arrangement, an unintentional opening of the perforation, for example by gripping the container in the region of the line of weakness 9 be reduced, with the perforation during the intended opening of the lid member 4 continue to rip in a simple way. Furthermore, a container wall with a perforation designed in this way has an increased stacking pressure which is increased in relation to the tangentially running perforation, as a result of which the stability or carrying capacity of such a wall can be increased.
